CARDING-MACHINE.

SPEOIFICATION forming part of Letters Patent No. 316,215, dated April 21, 1885.

Application filed October 6, 1884. (No model.)

To all whom t may concern,.-

Be it known that I, J oHN ABBOTT, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Oarding-Machines, of which the following is a specitication.

My invention relates to that class of carding-machines known as top-fiat cards;77 and it consists of an improved device for removing the particles of foreign matter collected in a carding-machine.

In the accompanying drawings, Figure 1 is a longitudinalsection of a top-flat carding-ma- Chine to which my improved cleaner has been applied; Fig.2, a perspective view of the cleaner detached, and Fig. 3 a transverse section of the cleaner drawn to an enlarged scale.

Referring to Fig. l, A is the frame of the carding-machine; B, the main cylinder; a a, the feed-rolls; D, the doffer, and b the cardlats, which cover about one-t-hird of the main cylinder, and are held in place on the frame by pins e, which pass through openings in each end of the flat. I replace the last flat of the series by my improved cleaner' attachment, which is constructed as shown in Figs. 2 and 3.

E is an elongated box, open at the bottom,`

and to the under side of this box is secured a blade or knife, F, adapted to present its beveled edge to the advancing teeth of the main cylinder B as the latter revolves when the attachment is applied to the machine. Between the front edge of the box and the knife is left a space, x, through which the foreign matter detached by the knife passes into the interior of the box.

It will be seen that the box is of about the same size in width and length as the ordinary flat, and is provided with openings e e at op` posite ends to fit over the usual retaining-pins, e, for the flats, so that the improved attachment may be readily applied to existing machines by simply removing the last flat now in use and replacing by the attachment without altering, modifying, or even stopping the carding-machine. rIhe attachment may also be as readily withdrawn again for inspection,sharp ening of the knife, or other purpose.

The box is shown as being somewhat deeper than the flats, in order to get the knife down into close proximity to the teeth of the cylinder, the ends of the box being cut away, as at f, for thispurpose. n

To the top of the box E is applied a detachable lid, G, which can be entirely removed without disturbing the box itself when it is desired to remove the foreign matters which have collected in the box. The lid G is provided with blocks g, Figs. 2 and 3, on its under side, to fit within the slot of the box and keep the lid in place,and the latter is extended to the full length of the box, as shown. Openings e2, Fig. 2, are provided to tit over the tops of the pins e.

I claim as my inventionl. The herein-described attach ment for toptlat carding-machines, said attachment consisting of an elongated box of the length and width of an ordinary fiat, and havinga cleanerknife at its under side, and at opposite ends openings adapted to fit the usual retainingpins for the iiats on the frame ofthe Inachine, substantially as set forth.

2. The herein-described attachment for topat carding-machines, said attachment consisting of an elongated box of the width and length of an ordinary flat, and adapted to be applied to the machine in place ofthe latter,

the box having applied to its top a detachable lid, and to its under side a knife, substantially as set forth. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN ABBOTT.
